[0031] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-12 An electrical control cabinet suitable for ships is shown, comprising a cabinet body 1 and a cabinet door 2 connected thereto; an equipment mounting plate 5 fixedly connected to the bottom plate of the cabinet body 1 is provided in the middle of the cabinet body 1, an upper passage for airflow to pass through is formed between the equipment mounting plate 5 and the top plate of the cabinet body 1, a condensation box 6 is nested and installed on the side of the equipment mounting plate 5 away from the cabinet door 2, the condensation box 6 is filled with heat transfer liquid, the condensation box 6 is connected to a liquid extraction pump 18 through a pipeline, the liquid extraction pump 18 is connected to an external evaporator 3, a condensation plate 7 is installed on the side of the condensation box 6 away from the cabinet door 2, the condensation plate 7 is abutted against a scraper 9, and the scraper 9 is connected to a reciprocating lifting mechanism that drives it to move up and down along the condensation plate 7;

[0034] A collecting tank 13 fixedly connected to the bottom plate of the cabinet 1 is provided below the scraper 9, a water collecting tank 1301 is provided on the side of the collecting tank 13 close to the condensation plate 7, and an air collecting tank 1302 is provided on the side away from the water collecting tank 1301, the air collecting tank 1302 is connected to an air pump 15 through an air extraction pipe 14, the air outlet of the air extraction pump 15 is connected to a spray hood 17 fixedly installed on the bottom plate of the cabinet 1 through an air outlet pipe 16, and the air outlet of the spray hood 17 faces the equipment installation plate 5;

[0035] The reciprocating lifting mechanism includes a guide plate 8 arranged on the outside of the scraper 9 and fixedly connected to the inner wall of the cabinet 1 at the upper end. The guide plate 8 is sleeved with a lifting frame 10 that is slidably abutted against it. The lifting frame 10 is clamped with an eccentric disk 11, and the eccentric disk 11 is connected to a driving motor 12; both ends of the lifting frame 10 are connected to the scraper 9 through a spring telescopic rod 20, and a sliding column 21 is fixedly connected to the inner side of the movable end of the spring telescopic rod 20. A lateral groove 801 that cooperates with the sliding column 21 is opened on the side wall of the guide plate 8, and the upper end of the lateral groove 801 is an arc-shaped structure, and the lower end of the lateral groove 801 is provided with an inclined groove 8011 and a groove extending below the inclined groove 8011 and extending to the bottom of the inclined groove 8011 and The extending groove 8012 connected to it and the connecting point of the inclined groove 8011 and the extending groove 8012 are hinged with a vertical plate 19. When the sliding column 21 moves to the position of the vertical plate 19, the vertical plate 19 is pushed outward and enters the extending groove 8012. The sliding column 21 entering the extending groove 8012 continues to move downward, so that the vertical plate 19 returns to a vertical state. Then the reciprocating lifting mechanism drives the sliding column 21 to move upward and is blocked by the vertical plate 19 and moves upward in the vertical direction. In this process, the scraper 9 changes from a contact state with the condensation plate 7 when moving vertically downward to a state away from the condensation plate 7 when moving vertically upward.

[0036] For details, please refer to Fig.12 When the cabinet 1 is dissipating heat, the air pump 15 and the liquid pump 18 are started. The air pump 15 sucks the gas in the cavity formed between the equipment mounting plate 5 and the guide plate 8 through the air suction pipe 14, and discharges the gas into the blowing hood 17 through the air outlet pipe 16. The blowing hood 17 blows the gas toward the equipment mounting side of the equipment mounting plate 5. The gas entering the equipment mounting side passes through the upper crossing channel above the equipment mounting plate 5 and enters the cavity between the equipment mounting plate 5 and the guide plate 8 again, thereby realizing a one-way flow tube of the gas in the cabinet 1 and passing through the electrical equipment on the equipment mounting plate 5 when flowing;

[0037] At the same time, the liquid pump 18 realizes the circulation of the heat transfer liquid between the condenser tank 6 and the evaporator 3, and the heat in the cabinet 1 is brought to the outside of the cabinet 1 through the heat exchange between the condenser plate 7 and the gas and the heat exchange between the condenser plate 7 and the heat transfer liquid of the condenser tank 6;

[0038] While the gas circulates in one direction in the cabinet 1 and the heat transfer liquid circulates inside and outside the cabinet 1, the high-temperature and high-humidity gas condenses on the condensation plate 7 when passing through the condensation plate 7 to form droplets adhering to the condensation plate 7, and the salt in the air flow dissolves in the droplets. The droplets containing the salt gather under the action of gravity and flow downward, and finally drip into the water collection tank 1301 of the collection tank 13, thereby removing the water and salt and collecting them in a centralized manner;

[0039] When it is necessary to clean the condensation plate 7, refer to Figure 6-8The driving motor 12 drives the eccentric disk 11 to rotate, and the eccentric disk 11 drives the lifting frame 10 to move up and down. The lifting frame 10 drives the scraper 9 to move up and down through the spring telescopic rod 20 to scrape the droplets on the condensation plate 7 and the precipitated salt particles, so that they fall into the sump 1301 of the collecting tank 13. It should be noted that, through the cooperation of the sliding column 21 installed at the movable end of the spring telescopic rod 20 and the lateral groove 801 provided on the side wall of the guide plate 8, the scraper 9 contacts the condensation plate 7 when moving downward and separates from the condensation plate 7 when moving upward, thereby realizing the one-way scraping of droplets and salt particles.

[0040] Compared with the traditional ship electrical control cabinet, the present invention is provided with an equipment installation plate 5 which is arranged in the cabinet body 1 and divides the cabinet body 1 into two independent chambers connected at the upper end, and a condensation plate 7 and a collecting tank 13 are installed in the chamber away from the electrical equipment. When heat dissipation is performed, the high-salt and high-humidity airflow is brought to the condensation plate 7 for centralized condensation through the airflow that circulates unidirectionally and passes through the electrical equipment, and the falling droplets of dissolved salt are collected by the collecting tank 13. At the same time, the heat is removed by circulating the heat transfer liquid inside and outside the evaporator 3 and the condensation box 6, thereby overcoming the corrosion of the electrical equipment caused by the random condensation and dripping of the high-salt and high-humidity airflow in the cabinet body 1; in addition, the droplets adhered to the surface of the condensation plate 7 and the precipitated salt particles are centrally cleaned by the scraper 9 that moves up and down, and the cooperation of the sliding column 21 and the lateral groove 801 is used to realize the unidirectional scraping and cleaning of the scraper 9, thereby improving the cleaning effect.

[0041] See also Figure 1 The cabinet body 1 is a hollow box structure, and a sealing ring bonded along the edge is provided at the contact position between the cabinet door 2 and the cabinet body 1. Electrical equipment is installed on the outer wall of the equipment mounting plate 5 facing the cabinet door 2. The cabinet body 1, the equipment mounting plate 5, and the shell of the condensation box 6 are made of uniform insulation material.

[0042] Specifically, the high-salt and high-humidity airflow is mainly condensed on the surface of the condensation plate 7, making the condensation position easier to control and more concentrated.

[0043] See also Figure 5 The condensation box 6 is a hollow box structure with an opening at the right end. The condensation plate 7 is fixed at the opening position at the right end of the condensation box 6 by bolts. The condensation plate 7 is flush with the right end surface of the equipment mounting plate 5.

[0044] Specifically, the scraper 9 can move vertically back and forth to scrape off the liquid droplets and precipitated salt particles on the surface of the condensation plate 7 .

[0045] See also Fig. 9The guide plate 8 is a plate-like structure with an inverted L-shaped cross section. The upper end of the guide plate 8 is fixedly connected to the top wall of the cabinet 1. The end surface of the guide plate 8 facing the condensation plate 7 is provided with vertically equidistantly distributed wave protrusions 803. The guide plate 8 is made of heat-insulating material.

[0046] Specifically, the wave protrusions 803 make the airflow passing through the cavity between the guide plate 8 and the equipment mounting plate 5 flow into an S shape, which facilitates the airflow to contact the surface of the condensation plate 7 multiple times and improves the condensation effect.

[0047] See also Figure 6 A central groove 802 is provided in the middle of the guide plate 8, a sliding block 1002 is fixedly connected to the lifting frame 10 on the side facing the guide plate 8 and is nested in the central groove 802, a longitudinal slide groove 1001 is provided along the length direction of the lifting frame 10 on the side facing the eccentric disk 11, and a traction column extending into the longitudinal slide groove 1001 is fixedly connected at the circumferential edge of the eccentric disk 11.

[0048] Specifically, the eccentric disk 11 drives the lifting frame 10 to move up and down along the guide plate 8, and has good stability.

[0049] In this embodiment, the spring telescopic rod 20 is a sleeve-type telescopic rod with a spring installed inside, which includes a sleeve fixedly connected to the lifting frame 10 and a movable shaft fixedly connected to the scraper 9. The cross-sections of the sleeve and the movable shaft are both regular polygons, and the sliding column 21 is fixedly connected to the movable shaft.

[0050] Specifically, the spring telescopic rod 20 can only be telescoped laterally and cannot rotate, so that the sliding column 21 always slides stably in the lateral groove 801.

[0051] See also Figure 8 A scraper strip 901 made of rubber material is bonded to the end surface of the scraper 9 facing the condensation plate 7.

[0052] Specifically, the scraping effect of the scraper 9 is improved.

[0053] See also Figure 3 The lower part of the cabinet body 1 is fixedly connected to a bottom cabinet 4 , and the air pump 15 and the liquid pump 18 are both installed in the bottom cabinet 4 .

[0054] Second implementation method:

[0055] Figure 4 , Fig.10 and Fig.11An electrical control cabinet suitable for ships is shown. On the basis of the first embodiment, a sealing plate 22 hinged to the inner wall of the water collecting tank 1301 is nested in the water collecting tank 1301, and a spiral conveying roller 23 nested in the water collecting tank 1301 is provided below the sealing plate 22. The spiral conveying roller 23 is connected to a conveying motor 25. The water collecting tank 1301 is connected to a slag discharge pipe 26 extending to the outside of the cabinet body 1 and provided with a valve. An extrusion column 27 is fixedly connected below the scraper 9. When the scraper 9 moves to the lowermost position, the extrusion column 27 squeezes the sealing plate 22 to make it rotate inward, so that the brine flows into the bottom of the sealing plate 22.

[0056] Specifically, by providing the blocking plate 22 and the squeezing column 27 and the spiral conveying roller 23 disposed in the water collecting tank 1301, it is convenient to centrally collect and discharge the salt water and salt particles.

[0057] See also Figure 4 The blocking plate 22 is hinged to the inner wall of the water collecting tank 1301 through a hinge shaft, and a torsion spring is installed on the hinge shaft to keep the blocking plate 22 in a horizontal state.

[0058] Specifically, the sealing plate 22 is kept in a normally closed state to improve the sealing performance of the inner cavity of the cabinet 1, and is squeezed open by the squeezing column 27 when removing salt water and salt particles.

[0059] See also Figure 4 and Fig.10 The guide plate 8 extends to the inner side of the water collecting tank 1301 , and a defogger plate 24 is fixedly connected between one end of the guide plate 8 close to the gas collecting tank 1302 and the inner wall of the water collecting tank 1301 .

[0060] Specifically, the mist entering the air collecting tank 1302 is reduced by the demister plate 24 .

[0061] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
